Abstract (en)
[origin: EP0409071A2] Apparatus (10) for reading a mold-identifying code in the form of a plurality of surface irregularities (76) extending in an arcuate array around the container heel (45) concentrically with the container axis. A starwheel conveyor (12) sequentially moves a series of containers (22) in an arcuate path about a conveyor axis (16) to and through a reading station (28). A belt (30) positioned adjacent to the conveyor periphery engages containers at the reading station and is driven so as to rotate the containers about their central axes. A light source (40) is imaged at the conveyor axis through container heel. A scanning mirror (50) is positioned to receive an image of the light source transmitted through the container heel and to reflect such image onto a camera (60). The scanning mirror is driven as a function of conveyor rotation so as to follow a container traveling through the reading station and reflect onto the camera an image of that circumferential portion of the illuminated container heel closest to the conveyor axis.
